restting a queue stl

To reset a queue in C++, you can follow these steps:

  1. Include the necessary header file: Begin by including the <queue> header file in your program to gain access to the queue container class.

  2. Create a queue object: Declare a queue object using the desired data type. For example, if you want to create a queue of integers, you can use the syntax queue<int> myQueue;.

  3. Add elements to the queue: Use the push() function to add elements to the queue. For instance, you can add an integer to the queue by calling myQueue.push(5);. Repeat this step for each element you want to add.

  4. Reset the queue: To reset the queue, you can assign a new, empty queue to the existing queue object. You can do this by using the swap() function. For example, you can reset the queue myQueue by calling queue<int>().swap(myQueue);. This creates a new empty queue and swaps it with the existing myQueue object, effectively resetting it.

  5. Verify the reset: If you want to ensure that the queue has been successfully reset, you can use the empty() function. It returns true if the queue is empty and false otherwise. For example, you can check if myQueue is empty by calling if (myQueue.empty()) { // queue is empty }.

By following these steps, you can reset a queue in C++ using the STL.
